FRANK J. WALTER, OF CHICAGO, ILLINOIS, ASSIGNOR, BY DIRECT AND MESNE ASSIGNMENTS, TO BENTON da WALTER MANUFACTURING COMPANY, CORPORATION OF ILLINOIS.

SPECIFICATION forming part of Letters Patent N o. 732,805, dated July 7, 1903. Application filed March 14, 1901. Serial No. 51,214. (No model.)

To all whom t may concern.:

Be it-known that LFRA'NK JWVALTER@ citizen of the United States,residingat Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Vest-Pocket Blow-Torches, of which the following is a specification.

My invention relates to a blowpipe such as is used by jewelers, plumbers, electricians, and for other purposes Where a small eX- a tremely hot flame is desired.

which air is blown into the second receptacle It consists of a. proper receptacle which is provided with a wick which is saturated with benzin, gasolene, or some similar burning fluid. When this Wick is ignited under the fordinary circumstances, it serves as a torch for illuminating purposes. Adjacent to this receptacle is another receptacle which has a blowpipe leading from it with its nozzle directed across the wick. A tube opens into this second receptacle and is 'preferably provided with a rubber-tube extension through which is filled with waste which is saturated With benzin, gasolene, or whatever burning fluid may be used in the first-mentioned receptacle. Before the air that is blown into the second receptacle can escape from the blowpipe it must pass through the saturated Waste, and as it passes out of the blowpipenozzle it carries with it a large quantity of the vapor of the burning fluid, so that the air from the blowpipe not only supplies oxygen to support the combustion and directs the flame to the point where it is desired, but it furnishes an additional amount. ofthe vapor to be burned. By this construction an unusually hot fiameis obtained, and a small,

compact, and unexplodable device is pro-V duced. l

Referring to the accompanying sheets of drawings, in which thc saine letters of reference are used io designate identical parts of all the figures, Figure l is a side elevation of the complete device. Fig. 2 is acentral seetion thereof on the line A A of Fig. 4. Fig. 3 is a section thereof on the line B B of Fig. 2, and Fig. 4 is a section thereof on the line CC of Fig. 1.

The wick-receptacle ct preferably takes the inthe receptacle a. as possible, the wick d or waste which may be used for filling a portion of the receptacle being saturated with the burning liuid. When a light is applied to the wick d, it will be apparent that an illuminating-dame will be furnished. The blowpipe-receptacle e may also take the form of a square tube and is preferably secured rigidly to the tube a. The blowpipe-tube f is.fas tened in the topof the receptacle e and, as seen in Fig. 2, extends down nearly to the bottom of the receptacle. Fastened in the upper end thereof is the short curved tube g, which terminates in the nozzle h, which is directed across the iop of the tube c in the customary position of ka blowpipe relative to the flame. A short curved tubej is secured in the cap It, which is screwed into a suitable aperture Z, formed in the side of the receptacle e, near its upper end. A rubber tube m has oue end drawn. over the outer end of the tubej, andA its other end may be provided with the nozzle n, if desired. When the device is not in use, a small cap o, which is secured to the top of the receptacle e by a small chainp, may be placed over the exposed end of the wick d, as indicated in Fig. l.

The operation of the device will be apparent. The receptacle e having been filled with waste q or some other absorbent material which is saturated with the burning duid, when it is desired to use the device as a bloWpipe all that is necessary is to take the mouthpiece n, if one is provided, between the lips and blow. The air entering the receptacle e at its upper end must pass down through the waste q before it can escape from the tube f through the nozzle h. Passing When a workman is using the device, it can be hung over the little finger by means of the curved tubej, which forms a sort of a hook, and in this way both hands are left free to be used as may be necessary.

By my invention I have produced an extremelysim ple, compact, convenient, and effective blowpije, and one that is useful and can be employed wherever an oxidizing or a reducing flame is desired.

While I have shown my invention as embodied in the form which I at present consider best adapted to carry ont its purposes, it will be understood that it is capable of some modifications, and that I do not desire to be limited in the interpretation of the following claims except as may be necessitated by the state of the prior art.

What I claim as new, and desire to secure by Letters Patent of the United States, is-

l. In a device ofthe class described, the com-` bination with the receptacle ct havingan opening for a wick therein, of a receptacle c connected thereto and having the tube provided with the blowpipe-nozzle directed over the wick of the receptacle a together with another tube through which air can be blown and entering said receptacle c so that air blown therein must traverse the length of the receptacle before it can escape from the blowpipe-nozzle, the caps I) and k closing apertures through which absorbent material can be introduced into the chambers a and e respectively, and absorbent material filling both of said receptacles and adapted to be saturated with a burning fluid; substantially as described.

2. In a device of the class described, the combination with the receptacle ct having an opening for a wick therein, of a receptacle c connected thereto and having the tube provided with the blowpipe-nozzle directed over the wick of the receptacle a together with an other tube through which air can be blown and entering said receptacle @,so that air blown therein must traverse thelengthof the receptacle before it can escape from the blowpipe-nozzle, the caps Z) and k closing apertures through which absorbent material can be introduced into the chambers CL and e respectively, and absorbent material lling said receptacle and adapted to be saturated with a burning fluid; substantially as described 3. In a device of the class described, the combination with the receptacle ct having the tube c opening from the upper end thereof, of the receptacle c secured thereto and having the blowpipe-tube with its nozzle directed over the upper end of the tube c and its end opening into the receptacle e near its bottom, together with the tubejl opening into the receptacle e near its upper end, the caps b and 7c closing apertures through which absorbent material can be introduced into the chambers a and e respectively,and absorbent material lling both ot' said receptacles and adapted to be saturated with a burning fluid; substantially as described.

4. In a device of the class described, the combination with the receptacle a having the tube c opening from the upper end thereof, of the receptacle e secured thereto and having the blowpipe-tube with its nozzle directed over the end ot' the tube c and extending substantially through the length of the receptacle with its other end opening near the bottom thereof, together with the tubej opening into the receptacle c near its upper end and curved downwardly to form a hook substantially as described.

5. In a device of the class described, the combination with the receptacle d having the tube c opening from the upper end thereof, of the receptacle e secured thereto and having the blowpipe-tube with its nozzle directed over the upper end of the tubec and extends ing substantially through the length of the receptacle with its other end opening near the bottom thereof, together with the tubej opening into the receptacle c near its upper end and curved to form a hook; and absorbent material iilling both ot said receptacles and adapted to be saturated with burning fluid; substai'itially as described.

G. In a device ot' the class described, the combination with the receptacle @having the cap b screwed into the upper end thereof and the tube c passing through said cap, of the receptacle e secured thereto and having the tubej" passed through the top thereof and extending substantially tothe bottom thereof and having the curved tube g in its upper end, terminating in the nozzle h directed across the top of the tube c and the cap 7.; screwed in the upper end of the receptacle c and provided with the curved tubej secured therein, all cooperating substantially as and for the purpose described.

In witness whereof I have hereunto set my hand this 26th day of February, 1901.

FRANK J. W'ALTER. In presence of J. H. MoELnoY, ANNA M. WAGNER.
